Unwinding failure with Node v24.11.1 (current LTS, both amd64 and arm64)

[christos68k]

Summary

I've noticed this after executing some test workloads for an unrelated issue. I also tested the following Node versions where unwinding works (both arm64 and amd64):

1. v20.19.1
2. v22.21.1
3. v23.11.1

To reproduce

$ nvm install v24.11.1
$ node --version
v24.11.1
$ node hello3.js

hello3.js

function bar(a, s) {
	a(s)
	//ads
}

function foo() {
	bar(a, "Hello world!")
}

console.trace("I am here");
a = console.log
while (1) {
	foo()
}

Expected output

Actual output

@gnurizen Maybe Polar Signals have a fix (IIRC you've previously contributed ARM64 Node.JS support) that you'd like to contribute?

I think @umanwizard you fixed this already, no?
